SPECIFICATION forming part of Letters Patent No. 307,841, dated November 11, 1884-.'

Application filed October 25, i883.

sAGNEs, a citizen of the Republic of France,

residing in the city of Paris, in the Depart" -ment ofthe Seine, have invented certain new and useful Improvements in the Transmission of Intelligible Signals by Electricity, and which I prefer to call "Steno-Telegraphy, and I do hereby declare that the following is an exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention having for its special object the application `of electricity to key-board stenographic machines generally, and especially to Michelas machine, in order to produce thereby a new and useful effect, Michelas machine having already secured Letters Patent No. 212, 724, February. 25, 1879, in the United States, I do not deem it essential to go very fully into the mechanical details of his apparatus.

Figure 1 represents a theoretical diagram showing one of my apparatus provided with its electrical connections and arranged as a transmitting-station. Fig. 2 represents the same arranged as areceiving-station. Fig. 3 is a general elevation of the machine, with fuller details as' to the mechanical parts. Fig. 4 is a side View of the same. Fig. 5 shows a plan of the machine.

The mechanism of Michelas machine consists of two essential parts: iirst, the printing mechanism; second,the mechanism to produce the automatic forward motion of the paper.

The iirst mechanism consists of akey-board divided into two halves symmetrically arranged, and having ten keys eachsix white keys, K, and four black keys, k. (See Figs. 3, 4, and 5.) These keys, when depressed by the operator, press. on twenty studs, b, and, through these vand the twenty rods a, move down the ends ofthe twenty metallic levers c. This pressure lifts up the styles d, placed at the other extremity of the lever-arms c, and having` each of them a sign or character en graved on its upper end. It is therefore suf- Iicient to depress one of the keys in order to lift the sign corresponding to it, andif several keys are depressed at the same time the cor- (No model.)

responding combination of signs will be reproduced on the paper.

The second part of the mechanism refers to l the automatic advance of the paper. This is produced by means of a small rod placed underneath the twenty keys, and which, when any one of them is pressed down, moves through a certain angle, all as shown in Patent No. 212,724. This angular motion sets into action a catch gearing with a -ratchetwheel, a, moves it,and through it a cylinder, a, so that the paper band rolled up on the drum h, which is placed between the two halves of the key-board, when caught between the two friction-rollers p and a, which pull it forward, is moved automaticallyat each impulse of the ratchet-wheel a, caused by the depression of one or more of the keys. A pressure-screw, f, allows of the regulation of the friction-rollers p and a. Guide-bars g are placed in the frame of the machine,to support the printingstyles d.

The inking in of the styles is effected by means of a ribbon well impregnated with some sort of slow-drying ink,and which moves from one roller to another, passing between the heads of the printing-styles and the paperl band to be printed upon, so that when any of the styles is lifted up it forces up the ribbon against the paper, and thereby the sign or character engraved on the head of the style is reproduced on the paper. The motion ofthe inking-ribbon need be only very slow, and to reach this result it is produced by means of a worm, s, and wheel t, as indicated in the drawings, Fig. 4.

It will bc apparent on inspection that when the ratchet-wheel a, producing the advance of the paper, is turned round it communicates its motion through a spur-gearing to the rod J r, carrying the worm s, which, on its turn, causes the-roller t to turn round, only with a much slower speed. This roller pulls forward the ribbon fu, which is uncoiled from roller to, on which it was stored up formerly, passes under the paper band, and is rolled up on the cylinder that carries the roller t. So much for the purely mechanical part of the apparatus. It is evident, however, that if the depression of the keys can be produced through any 4the receiving-station.

other agency than the pressure of the lingers the same eect will arise from similar causes, and the mechanism will be set in action. Electricity furnishes an easy and convenient agent for obtaining such results by means of electro-magnets provided with their armatures, connections, and all proper appliances.

I shall now proceed to describe the arrangement illustrated on the'drawiugs, and whereby I am enabled to transmit to any distant station the stenography which up to the present time is produced only on the spot where the words emitted are recorded.

Fig. 1 gives a theoretical diagram of my apparatus arranged as a transmitting-station.

The full lines represent the line-circuit and the dotted lines the local circuit. It will be observed that in this case the commutator F, placed on the local circuit, is open, also the shuntbar G, destined to short-circuit the manipulatingkeys K and 7i.

For the transmission of a signal, when the key K is depressed, contact is established between its iron armature X andthe core ot' the electro-magnet E, thereby closing'the circuit of the line-battery H. Consequently a current will ow from battery H through wire 4, post 10, wire 9, core of the electro-magnet E, armature X, wire 8, relay'R, (whose armature will be depressed, but with noeITect, as the local commutator F is open.) wire 6, post 1l, relay R', shuntbar G', wire 12, post 13, wire 14, line-battery H', wire 15,fand back .to line-battery H, Fig. l. Y

It will be noticed that on Fig. 2, which is arranged as a receiving-station, local commutator F is closed, and also shunt-bar G'.

Therefore, the current coming from the transmitting-station, on its passage through the electro-magnet of relay It', will attract its armature, thereby closing the local circuit of The current fromlocal battery I' will therefore flow through armature of relay R', thence through coils of electromagnet E', commutator F', and back to I. On its passage through E' the current will polarize the core of the electro-magnet, thereby causing it to attract its armature X', and thus causing the depression of the key 7c'. This depression will put in motion the mechanism described in the rst part of this paper, producing the same effect as if the apparatus had been manipulated directly with the iingers.

On the drawings, Figs. l and 2, Y and Y represent the rods connected with the levers and counteracti11g-springs already spoken of. The actions of commutators F and'F' and of shunt-bars G and G will be clearly understood from the drawings. For example, in

Fig. 1, if commutator F remained closed,.the transmission of a signal would act on the relay R, close the local circuit, attract the key K, which could not then be released again for the transmission of the following signals, and would remain iixed to the core of the electromagnet E. Similarly, in Fig. 2, shunt-bar G' short-circuits the keys K', and prevents, on their depression at the reception of a signal, their transmitting back the same signal to the other station. This explanation has been given for one key only. It is clear, however, that the same actions would take place when any number of keys at a time are depressed, there being a separate circuit for each key which is depressed.

Figs. 3, 4, and 5 will give a better idea of the i way the connections are made in the actual apparatus.

Fig. 3 gives iu elevation two views of theA machine. On the left-hand side the electromagnets and electrical connections are supposed to be removed, so as to show the internal mechanism already described. On the right-hand side are shown the electro-magnets E E Eacting on the keys K K lc k through their armatures X X X .r :c x. Bindingpost 10 is fixed on the two mains 16 and 17 (see Fig. 5,) which are connected with the cores ofthe electromagnets E E E. Binding-post 18 is {iXed on the two mains 19 and 20 (see Fig. 5,) which are connected with one extremity of the coils of the electro-magnets E E E. The other extremities go to the posts P I? I). The posts P' Il P' are connected through wires 8 8 8 with the armatures X X m :c of the keys. These posts P' P' P', moreover, are provided with metallic hooksSSS, on which rests the shuntbar G when closed. This bar, as shown on plan in Fig. 5, has a binding-post at one end, so as to make the connection with post 10.

I call attention to the reversibility of the two apparatus, whereby they can be used at will as receivers or as transmitters by asimple change in the mode of connection.

I claim- 1. The combination of a series of keys carrying series of armatures with their electromagnets and with the levers of a type-writing machine for printing marks on paper, and means for feeding the paper. all arranged so that each key, when depressed, will actuate the type-writer and at the same time close a local circuit, as specified.

2. The combinationof two type-writing machines with armatures attached to'their keys, electro-magnets, and electric conductors, all arranged to enable the operating ot' both machines simultaneously by the depression of the keys of one of said machines, as specified.
